SPECIFICATION forming part of Letters latent` No. 534,910, dated February 26, 1895.

Application filed May' 23, 1 94.

.To @ZZ whom it may concern:

Be it known that l, HORACE SMITH OvnasTREET, of York, in the county of York and State of Nebraska, have invented Aa new and Improved Oultivator, of which the following is a full, clear, and exact description.

cultiva-tors and it has for its object to provide a cultivator which may be utilized lfor cultivating a field unplanted, serving sub` stantially as a harrow, or it may likewise be employed for cultivating two rows of corn at one time.

A further object of the invention is to provide a means whereby all of the gangs of cultivator blades may be independently manipulated, namely, raised or lowered, and whereby the end or .outer gangs may be adjusted as to depth, the intermediate gang when released, serving as a drag.

Another object of the invention is to provide a draft mechanism under thorough control of the driver, the said mechanism being so constructed that the poles employed may be directed to the right or to theleft, causing the team to properly guide the machine.

Another object of the invention is to provide an equalizer used in connection with the said draft tongues, whereby all undue tension,

will be removed from the team, and whereby three horses may be employed, each of them drawing an equal amount of weight.

Another object of the invention is to provide a means whereby the gangs of cultivators will not have lateral movement, being firmly held in the position in which they may be placed.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar Iigures and letters of reference indicate correspondingpartsin all the views.

Figure 1 is a plan view of the improved cultivator. Fig. 2 is a longitudinal section taken essentially on the line 2-2 of Fig. 1. Fig. 3 is a transverse section taken practically on the .line 3--3 of Fig. 1; and Fig. 4 is a front elevation of the beam of an end gang `its moving laterally.

of cultivator blades, illustrating the manner in whichthe said beam is pivoted to prevent I In carrying out the invention the main frame of the machine is made substantially y in duplicate, comprisinga lower section Aand My invention relates to an improvement in `an upper section B, the two sections being placed one directly over the other or practi cally so. The lower section A of the frame comprises a front beam l0, a rear beam 11 and end beams 12, the end beams being preferably parallel and made to extend a suitable distance rearwardly. B of the frame consists of a front bar or beam' 1Qa and a rear bar or beam 11a, located over corresponding beams of the lower section of the frame, being separated therefrom a predetermined distance through the medium of end bars 12a, the said end bars or beams of this upper section of the frame extending longitudinally across the lower section, being made to converge at their rear ends; and the said end beams 12a, project some distance in a rearwardly direction. The two sections of the frame are farther spaced through the medium of a central beam 13, located between and attached to the sections, and made likewise to extend well to the rear, the rear extremity of this central beam being utilized ordinarily as asupport for the drivers seat 13a.

The axle spindles 14, are secured to the ends of the lower section A of the frame, and are adapted to carry ground wheels 15 usually The upper section/6 5 prises two poles 16 and 17, located one at each side of the center of the machine. These poles extend rearward through the space between the two sections of the frame, being pivotally attached to the front beams of said sections, as shown at 18 in Figs. 1 and 2; and the said poles usually project beyond the rear beams ofthe sections ofthe frame, and have attached to their rear extremities shoes 19, said shoes being provided with openings in which frietion rollers 20, are journaled, as shown in Fig. 2, the rollers being adapted to engage with the rear beams ofthe frame, and thus facilitate the lateral movement of the poles. The rear ends or shoes of the poles are connected by a bar 2l in a pivotal manner; and a link 22, is pivoted to the connecting bar 2l at one side of its center, the other end of the link IOO being pivotally attached to a lever 23, fulcrumed usually upon the central beam 13; and the said lever is provided with apertures 24, through the medium of which the link 22 may be shifted as to position, in order to provide more or less leverage in the operation of the lever 23, as through said lever the poles are directed to the right or to the left, as may be demanded to guide the machine, since the machine is to be guided by the action of the team.

In connection with the poles 16 and 17 an equalizing device is employed, and said equalizing device comprises two equalizing bars 25, located one beneath each pole 16 and 17, and adjustably and pivotally connected between their centers and outer ends with brackets 26, or their equivalents, attached to the outer faces of the poles, as illustrated best in Fig. 1. Aperpendicular pendent link 27, is connected with the outer end of each equalizing bar 25, and at their lower ends the said links are held in a predetermined position by braces 28, connected with them and a liXed support on the machine.

Each link is adapted to adjustably carry a singletree 29, the said singletrees being usually connected with the links through the medium of chains 30, or their equivalents. A third singletree 3l, is employed, located between the poles 16 and 17. This singletree is adjustably connected with a perpendicular pendent link 32, connected with a fixed support at its lower end by a brace 33. The upper end of the link has attached to it the casing of a pulley 34, and the said pulley casing is connected by a spring 35 with an arm 36, projected forwardly from the central portion of the machine frame, as shownin Fig. 3,and an equalizing connection is provided between the inner ends of the two equalizing bars 25, by passing a cord, chain or cable 37, attached to said ends, over the said pulley 34, and shown in Figs. 1 and 3.

In connection with the frame of the machine, preferably three gangs of cultivators are used, a central gang D, and two outer or end gangs D. The end gangs D', are connected with the forward portion of the frame through the medium of stirrups 38, projected downward from the forward end portions of the frame,one of which stirrups is shown in detail in Fig. 4, and the central gang is connected with the frame through the medium of a corresponding yet longer stirrup 39, shown in dotted lines in Fig. l and in full lines in Fig. 3. The stirrups are connected with the frame of the machine through the medium of rearwardly-extending braces 40, each of which may be provided with a turnbuckle 4l, in order that the stirrups may be rectified when occasion may demand.

Each end gang of cultivators comprises a beam 42, having attached at opposite sides forwardly and downwardly extending shanks 43, one located in advance of the other, said shanks being suitably braced by bars 44.

These shanks are preferably curved outwardly from the beam in order that the shovels or blades 45, carried by their lower ends, will enter the ground beyond the sides of the beam; and it will be understood that any form of share blade or shovel may be substituted for the shovels illustrated in the drawings.

The forward end of each beam of the gangs D is provided with a shoe 46, (see Fig. 4) adapted to be carried around or to turn upon a pivot pin or bar 47, adjustably located in each of the stirrups 38, said shoe being provided with an opening at its pivot point; and said opening is usually centrally located, and receives a collar 48, located upon the pivot pin. In this manner the beams of the gangs D are free to move upward or downward, but can not have lateral movement. These gangs are raised and lowered through the medium of levers 49, preferably fulcrumed upon the rear extensions of the end. bars 12 of the upper section of the frame, the said levers being provided with the usual thumb latch to engage with racks 50, located also upon said end bars; and the levers are adjustably connected with the beams through the medium of links 51. In this manner it is evident that the beams may be readily raised and lowered and held in predetermined position.

With reference to the intermediate gang D, said gang comprises two beams 52, arranged parallel and connected by cross bars 53, said cross bars being also made to carry a short beam 54, shown in Fig. 3. Shanks 55, are projected downward and forward from the outer faces of the beams 52, and like shanks 56, are projected in similar manner from opposite sides of the short beam 54, whereby usually the central gang is made to carry four Shanks, and consequently four cultivator blades 57 of any approved construction. The beams 52 of the central gang are provided with shoes in like manner as the beams of the end gangs, but the shoes are not used in connection with a collar, since one of the beams will be in engagement with each member of the stirrup 39, thus preventing the beams from having side movement. The forward ends of the beams are pivoted upon a spindle 39a, adjustably located in the central stirrup 39.

The central gang is not ordinarily provided with levers for raising and lowering it, being held in a lower position by springs attached to the frame and the seat beam 13, although a hand lever may be used, but the gang is held in an upper position when not required for use, by means of a lock lever 58, which will engage with one of the cross bars 53, as shown in Fig. 3.

In the operation of cultivating corn two rows will be cultivated at one time by the use of this machine, the rows of corn being located between the cultivator blades, or the outer portion of the centrat gang and inner portions of the end gangs. The side gangs maybe brought into use independently of the IOC IIO

central gang, or the central gang may be brought into action when the side gangs have been elevated.

A truss rod provided with a suitable tension device is located upon the under side of the axle, as shown in dotted lines Fig. l to prevent the axle from springing.

Having thus described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a cultivator, the combination, with a frame, and a bracket projected downward from the frame, provided with a spindle, of a longitudinal beam adapted to carry cultivator blades, the said beam being provided with a shoe at one end, mounted to turn upon the said spindle, the said shoe being provided with an opening, and a collar formed upon the spindle, located inthe said opening, so as to abut laterally against the walls of the opening in the shoe as and for the purpose set forth.
